Subject: test(installed-versions): verify the PHP class the worker loads

InstalledVersions has no Rust port, so the skeletons left behind asserted
nothing about compatibility. The tests now require the Composer checkout's
vendor/autoload.php into the PHP worker and drive the real class there, which
puts $selfDir, the registered ClassLoader and Composer\Semver\VersionParser in
the same state as the upstream PHPUnit run. The upstream setUp reflection and
the installed_relative.php require stay in PHP; the expected values are Rust.

The class Composer's own vendor directory autoloads and the one
FilesystemRepository::write dumps from include_str! are separate files, so an
added test asserts they hold the same bytes.

FilesystemRepositoryTest::testSafelyLoadInstalledVersions moves to the worker
too, against the php/stubs FilesystemRepository, whose safelyLoadInstalledVersions
runs the PCRE recursive grammar natively.

The shared worker helpers live in tests/common/php_worker.rs.
